[pdal] Filters on LiDAR data for vegetation cover

[Silvia Franceschi]

Thanks Luigi,
it is exactly what I am doing, but regarding filters, I noticed that there
are many other filters and I was wondering if there were something else to
use specifically for vegetation or dense cover.

I am also reading some papers, it is hard to find specific tests on
vegetation, the buildings seems to be more interesting!!! :-D

Hear you soon!!
Ciao

Silvia
